| 摘 要： | 基于大跨空间结构振动主动控制方法,以超磁致伸缩材料为核心元件,充分利用其输出力大、响应速度快、可靠性高、驱动电压低等优良磁控特性设计出一种将电磁能转化为机械能的减震控制装置—超磁致伸缩作动器,分析了其工作原理和设计方法,然后对其进行力和位移输出性能测试.结果表明,该作动器磁路结构良好,磁机转换效率较高,在驱动电流作用下可输出较大的力和位移,其与驱动电流基本呈线性关系且对电流的变化非常敏感,为这种作动器在大跨空间结构中的应用打下了良好的基础.

| Abstract: | According to active vibration control of the large spatial structure,a vibration control device called giant magnetostrictive material actuator(shorted as GMMA) was designed which could convert electromagnetic energy into mechanical energy.This device takes giant magnetostrictive material as the core component and makes full use of its magnetic properties like big force output,fast response,high reliability and low driving voltage.Then its principle and design method was analyzed,and output performance tests were done.The results show that this device has good magnetic circuit structure,high efficiency of energy conversion,and could produce larger force and displacement under the drive current with linear relationship sensitively,and lay a good foundation for its application in the large spatial structure. |
